Hi, we want to setup a page on facebook that allow users to register for our newsletter. Am looking at various apps but so far did not find a good match. Basically we would like to design the page and when a user enters the email address, we would like to real-time push that to our website so that his registration is complete and he receives a thankyou email instantly.

Can you suggest a good free/paid app or tool that can help us do this.
